may whom-it may'concem: I i B :itknown that 1?, Louis M. NELSON, residing at Douglas, the"cou11 ty-- of'Conve'rse and State of 'Wyoming, have' invented certain new'and useful Improvements in Tires, of which .thefollowing-is a s ecification. I

This invention compre ends certain new and useful rovements in tires for the wheels of vehic es',-particularly automobiles and'automobile trucks, and the invention has'for its object a 'nijvel construction of tire which will embody characteristics of sim licity,"durability, and the capability of wi listandin hard. usage, especia ly with heavy vehic es' and over heavy roads that have suchan injurious abrasive efiect on the ordinary rubber tires of the cushion and pneumatic type; the invention at'the same time 'roviding a tire which will possess substantially the same resiliency assuch rubber tires.

With this and other objects in view as will more fullyfappear as" the description procoeds, the invention consists in certain features of constructionand arrangement and combinations of the parts that'I shall hereinafter'fu'll describeand claim.

For a ullunderstandingfof the invention,

. erence is'to be had' to -the following description and "accompanying i drawings, in

which: n

a Figure 1 is a longitudinal sectional view of a. tire constructed in accordance with my invention; Fig. 2 is a horizontal sectional view on the line 2-2 of Fig.1; Fig. 3 is a transverse sectional viewon the line '3-3 of Fig. 1; Fig. 4 isa similar viewon a reduced scale, the section being taken on .the line 44 of Fig. 1;v Fig. 5 is a detail view of the worm. Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The body portion of my improved tire is' preferably composed of a plurality of sections 1 of leather or "some e uiva ent substance or material that is capa 1c of resisting the abrasive action, incidental to the use of vehicle Wheels,- said sections being arranged in abutting relation to each other, face to face, the faces tapering toward one end to a sufficient extent to produce a circular series of the predetermined diameter. The inner ends of the sections may be reduced as indicated at 2 for locking engagement with j the i specification of Late"..- Pateht; ApplicationfiledAugust 5, 1908; Serial No. 447,110.

The sections 1 are'formedwith one or more apertures extending therethrough, said apertures being two in number in the present each wire being'oppositely threaded as inwith threads corres onding to 'the right and left hand. threa s of the ends.of the tie wires, with sections- 1 being cut out to receive it; an

'tached and replaced or have others substituted for them without impairin the sillciency of the tire, although it is to ie understood that I do not contemplate the necessit for such relplacemept or substitution as it 1s manifest t at the inherent integral or one;- piece construction. of the several sections and the material or substance (leather) out of which the sections are preferably com osed will enable the sections to successully withstand or resist the abrasion between a road surface and the tread and side portions of the tire, the latter in particular,-

which has been found so fatal to pneumatic tires. It is to be understood that the body portion of my tire is complete in the sections 1, without any envelop or cover, the same not being necessary owing to the character of the substance out of which the sections are formed;

Having thus described the invention, what I is claimed as new is i. The herein described tire, comprising at extending bores, tie Wires accommodated in said bores and formed with oppositely threaded extremities, coupling sleeves having threaded engagement with said threaded extremities, a casing mounted in the body of the tire, the sleeves being mounted to rotate in said casing and provided with Worm gears, a worm mounted in said casing and meshing with said worm gears, and means for turning said worm;

2. The herein described tire, comprising a body portion, tie wires embedded therein and formed with oppositely threaded oX- tremities, coupling sleeves formed with internal threads engaging said threaded extremities, a casing mounted within the body portion of the tire, a s indle journaled in said casing and provide with a head, said head being formed with a worm, and worm gears mounted upon and movable with the coup ling sleeves and meshing with said worm.

3. The herein described tire, comprising a body portion, a tie wire embedded therein and formed with oppositely threaded extremities, a coupling sleeve formed with inter-- nal threads engaging the said threaded extremities,-a casing embedded in the body portion of the tire and in which the coupiing sleeve is mounted to rotate, said casing being formed with a transverse'slot, a worm mounted in said slot,'the coupling sleeve being provided 5 with a Worm gear with which said worm meshes, the casing being further formed with an inwardly facing opening leading to said slot, and a radially extending spindle journaled in said opening and secured to said worm to turn the same.

4. The hereln described tire, comprising a body portion, tie wires embedded in said LOUIS M. NELSON. [L. s.]
